Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0064] Embodiment 1

[0065] To facilitate understanding of this application, Figure 1 The contents described in the flowchart of a gateway switching method provided in the first embodiment of the present invention are described in detail in the first embodiment of the present application.

[0066] See also Figure 1 As shown, Figure 1 A flowchart of a gateway switching method provided in Embodiment 1 of the present invention is shown, which is applied to a power supply controller of a gateway switching system, wherein the system further comprises a main gateway, a backup gateway, a gateway status monitor and a main power supply, wherein when the main power supply supplies power to the main gateway, the main gateway sends a first inquiry signal for detecting the status of a first communication link between the main gateway and a device terminal to a terminal device once every preset sending time, the main gateway sends a second inquiry signal for detecting the status of a second communication link between the main gateway and the platform end to a platform end once every preset sending time, and the gateway status monitor sends a third inquiry signal for detecting the operating status of the main gateway to the main gateway once every preset sending time, wherein the method comprises steps S101 to S102:

[0067] S101: After each time a first device sends an inquiry signal to a second device, monitor whether the first device receives a response signal fed back by the second device based on the inquiry signal within a preset response time, wherein the first device is a device that sends an inquiry signal and the second device is a device that receives an inquiry signal.

[0068] Specifically, a gateway is a computer system or device that performs conversion tasks and can serve as a communication intermediary to connect two systems or devices with different communication protocols, data formats or architectures; the main gateway and backup gateway in this application are gateways used to connect the Internet of Things platform and the user device terminal. When the gateway is enabled, the main power controller is first used to control the main power supply to supply power to the main gateway to enable the main gateway; when the main gateway can work normally, the backup gateway is not enabled, and only the main gateway is guaranteed to operate.

[0069] When the main gateway is working, it establishes communication links with the device terminal and the platform end respectively to realize data communication between the device terminal and the platform end; when the first communication link between the main gateway and the device terminal, or the second communication link between the main gateway and the platform end, or the main gateway itself is abnormal, the device terminal and the platform end cannot perform normal data communication; in order to determine whether the device terminal and the platform end can realize data communication, it is necessary to monitor the operating status of the first communication link, the second communication link and the main gateway itself respectively.

[0070] When the main power supply supplies power to the main gateway, the specific monitoring method is as follows: when detecting the first communication link, the first device is the main gateway, and the second device is the device terminal, that is, the main gateway sends a first inquiry signal to the terminal device once every preset sending time for detecting the state of the first communication link between the main gateway and the device terminal; when detecting the second communication link, the first device is the main gateway, and the second device is the platform end, that is, the main gateway sends a second inquiry signal to the platform end once every preset sending time for detecting the state of the second communication link between the main gateway and the platform end; when detecting the operating state of the main gateway itself, the first device is the gateway state monitor, and the second device is the main gateway, that is, the gateway state monitor sends a third inquiry signal to the main gateway once every preset sending time for detecting the operating state of the main gateway.

[0071] S102: If the first device does not receive a reply signal fed back by the second device based on the inquiry signal within a preset reply time, control the main power supply to perform a master-slave switch to stop using the main gateway and start the backup gateway.

[0072] Specifically, when the first device is the main gateway and the second device is the device terminal, if the first device does not receive the reply signal fed back by the second device based on the inquiry signal within the preset response time, it means that the first communication link has failed; when the first device is the main gateway and the second device is the platform terminal, if the first device does not receive the reply signal fed back by the second device based on the inquiry signal within the preset response time, it means that the second communication link has failed; when the first device is the gateway status monitor and the second device is the main gateway, if the first device does not receive the reply signal fed back by the second device based on the inquiry signal within the preset response time, it means that the main gateway itself has failed.

[0073] When any of the above situations occurs, the communication between the device terminal and the platform cannot be achieved through the main gateway. It is necessary to control the main power supply to perform master-slave switching to stop using the main gateway and start the backup gateway to achieve communication between the device terminal and the platform.

[0074] In a feasible implementation, each time after the first device sends an inquiry signal to the second device, after monitoring whether the first device receives a response signal fed back by the second device based on the inquiry signal within a preset response time, the method further includes:

[0075] If the first device receives a reply signal fed back by the second device based on the inquiry signal within a preset reply time, the main power supply is controlled to continue to supply power to the main gateway.

[0076] Specifically, if the first device receives a reply signal from the second device based on the inquiry signal within a preset reply time, that is, when the first device is a main gateway and the second device is a device terminal, if the first device receives a reply signal from the second device based on the inquiry signal within the preset reply time, it means that the first communication link is not faulty; when the first device is a main gateway and the second device is a platform end, if the first device receives a reply signal from the second device based on the inquiry signal within the preset reply time, it means that the second communication link is not faulty; when the first device is a gateway status monitor and the second device is a main gateway, if the first device receives a reply signal from the second device based on the inquiry signal within the preset reply time, it means that the main gateway itself is not faulty; when the first communication link, the second communication link and the main gateway itself are not faulty, it means that the main gateway can realize communication between the device terminal and the platform end, and the main power supply continues to be used to power the main gateway.

[0077] In one possible embodiment, see Figure 2 As stated, Figure 2A flowchart of a fault status sending method provided by the first embodiment of the present invention is shown, wherein when the first device is a main gateway and the second device is a device terminal, after each time the first device sends an inquiry signal to the second device, after monitoring whether the first device receives a reply signal fed back by the second device based on the inquiry signal within a preset reply time, the method includes steps S201 to S202:

[0078] S201: If the first device does not receive a reply signal fed back by the second device based on the inquiry signal within a preset reply time, the failure state of the main gateway is marked as a terminal access unit failure of the main gateway.

[0079] S202: Send the fault status of the main gateway to the platform end.

[0080] Specifically, when the first communication link fails, the fault state of the main gateway is marked as a terminal access unit failure of the main gateway, and the fault state of the main gateway is sent to the platform end so that the administrator of the platform end can know the fault state in time.

[0081] In one possible embodiment, see Figure 3 As stated, Figure 3 A flowchart of another fault status sending method provided in the first embodiment of the present invention is shown, wherein when the first device is a main gateway and the second device is a platform end, after each time the first device sends an inquiry signal to the second device, after monitoring whether the first device receives a reply signal fed back by the second device based on the inquiry signal within a preset reply time, the method includes steps S301 to S303:

[0082] S301: If the first device does not receive the reply signal fed back by the second device based on the inquiry signal within the preset reply time, monitor whether the first device receives the reply signal fed back by the second device based on the inquiry signal within the preset reply time when the first device is the gateway status monitor and the second device is the platform end.

[0083] Specifically, when the second communication link fails, it is necessary to further determine whether it is because the main gateway cannot connect to the Internet or because the main gateway cannot connect to the platform server; then, when the first device is the gateway status monitor and the second device is the platform end, monitor whether the first device receives the reply signal fed back by the second device based on the inquiry signal within the preset response time.

[0084] S302: If the first device is the gateway status monitor and the second device is the platform end, and within a preset response time, the first device receives a response signal from the second device based on the query signal feedback, then the fault state of the main gateway is marked as a network unit failure of the main gateway.

[0085] S303: Send the fault status of the main gateway to the platform end.

[0086] Specifically, under normal circumstances, it is impossible for the main gateway to be unable to connect to the Internet and the main gateway to be unable to connect to the platform server at the same time. Therefore, when the first device is the gateway status monitor and the second device is the platform end, within the preset response time, the first device receives the reply signal fed back by the second device based on the inquiry signal, indicating that the second communication link fails because the main gateway can connect to the platform server but the main gateway cannot connect to the Internet. In this case, the failure state of the main gateway is marked as a network unit failure of the main gateway.

[0087] In one possible embodiment, see Figure 4 As stated, Figure 4 A flowchart of another fault status sending method provided by Embodiment 1 of the present invention is shown, wherein when the first device is the gateway status monitor and the second device is the platform end, after monitoring whether the first device receives a reply signal fed back by the second device based on the inquiry signal within a preset reply time, the method includes steps S401 to S402:

[0088] S401: If the first device does not receive a reply signal fed back by the second device based on the inquiry signal within a preset reply time, the failure state of the main gateway is marked as a connection failure with the platform server.

[0089] S402: Send the fault status of the main gateway to the platform end.

[0090] Specifically, if the first device does not receive a reply signal fed back by the second device based on the inquiry signal within the preset response time, it means that the second communication link fails because the main gateway can connect to the Internet but the main gateway cannot connect to the platform server. In this case, the failure state of the main gateway is marked as a connection failure with the platform server.

[0091] In one possible embodiment, see Figure 5 As stated, Figure 5A flowchart of another fault status sending method provided in the first embodiment of the present invention is shown, wherein when the first device is the gateway status monitor and the second device is the master gateway, after each time the first device sends an inquiry signal to the second device, after monitoring whether the first device receives a reply signal fed back by the second device based on the inquiry signal within a preset reply time, the method includes steps S501 to S502:

[0092] S501: If the first device does not receive a response signal fed back by the second device based on the inquiry signal within a preset response time, the failure state of the master gateway is marked as a failure of the main control unit of the master gateway.

[0093] S502: Send the fault status of the main gateway to the platform end.

[0094] Specifically, when the main gateway itself fails, the failure state of the main gateway is marked as a failure of the main control unit of the main gateway, and the failure state is sent to the platform end.

[0095] In a feasible embodiment, the system further includes a backup power supply, and the method further includes:

[0096] When it is detected that the main gateway is disconnected from the main power supply, the backup power supply is enabled to supply power to the main gateway; or, when it is detected that the main gateway is disconnected from the backup power supply, the backup power supply is enabled to supply power to the backup gateway.

[0097] Specifically, the system also includes a backup power supply. When the main power supply can work normally (when the main gateway or the backup gateway is powered normally), the backup power supply is not put into use. When it is monitored that the main gateway is disconnected from the main power supply, the backup power supply is enabled to power the main gateway, or when it is monitored that the main gateway is disconnected from the backup power supply, the backup power supply is enabled to power the backup gateway, so as to ensure the normal operation of the main gateway or the backup gateway by supplying power through the backup power supply when the main power supply cannot be supplied.

[0100] When the main power supply supplies power to the main gateway, the main gateway is used to send a first inquiry signal for detecting the state of a first communication link between the main gateway and the device terminal to the terminal device once every preset sending time, and is also used to send a second inquiry signal for detecting the state of a second communication link between the main gateway and the platform end to the platform end once every preset sending time, and the gateway state monitor is used to send a third inquiry signal for detecting the operating state of the main gateway to the main gateway once every preset sending time;

[0102] If the first device does not receive a response signal fed back by the second device based on the inquiry signal within a preset response time, the power controller is used to control the main power supply to perform a main-standby switch to stop using the main gateway and start the standby gateway.

[0105] In a feasible implementation scheme, when the first device is a main gateway and the second device is a device terminal, the power controller is used to monitor whether the first device receives a reply signal fed back by the second device based on the inquiry signal within a preset reply time each time the first device sends an inquiry signal to the second device, and is also used to:

[0106] If the first device does not receive a reply signal fed back by the second device based on the inquiry signal within a preset reply time, the fault state of the main gateway is marked as a terminal access unit failure of the main gateway;

[0107] The fault status of the main gateway is sent to the platform end.
